My sister's problem is the opposite. Updated her 2G iPhone to 3.0, everything works great. She's on prepaid in Australia so she's turned off 3g (not that it would work) and edge but she's still able to connect to the internet. I was wondering if APN editing still works for 3.0. I'm thinking of having her install it and put in bogus settings for the APN to hopefully disable internet. Any advice is welcome. Thanks!
